A look 'round the AFC West: the Raiders and Chargers still need help on the offensive line, the Broncos need to shore up their middle linebacker spot, and the Chiefs are looking for receivers not named Dwayne Bowe to step up.

The Patriots need the pass rush to step up, the Bills need more consistent work from their cornerbacks, the Dolphins hope Johnathan Martin can adequately protect Ryan Tannehill, and Geno Smith hopes he has someone to throw to in New York.
